The ability to set different wallpaper for each activity is excellent in KDE, but it is very hard to browse through the cluttered collection of wallpaper in “Image” plugin
A wallpaper plugin is needed (Different from Slideshow as it does not allow to select a specific wallpaper) that would
(1) Assign different wallpaper folder for each activity similar to Slideshow based plugin for selection
(2) Images only appear in selection screen once a folder is selected to avoid cluttered view
